The arm 10 carries anadmovable between the nozzle plates 20, 21 and in justable weight 13 bymeans of which the desired a slot formed in the closure member 19whereby pressure is applied to the rod through the pawl, the plate 24may be moved towards or away from the arm and its weight being raised byhand when the peripheral surface of the past ng (C. The required as thearm sinks. adjustment of the plate 24 may be effected by 11screw-actuated cam means. Thus the plate may be provided with a toothengaging in a slot 26 in an adjustable block 27 located in a guidinggroove 28 in a cap-piece 29. In this way the thickness of the film ofpaste taken up by the pasting disc may be regulated as desired while themachine is running.

The opposite end wall of the nozzle maybe formed as a separate removableplate 30 which closes the rear end of thenozzle and also acts as ascraper for removing dried paste from the edge of the disc before itpasses into receiving relation with the nozzle. Theplate 30 is locatedin a groove formed in the closure member 19 and is held in set positionby the screw 31. A scraper 42 is pivotally mounted on the gear casing at.43 whereby it may be moved in engagement with the pasting disc (seeFigure 1) spring means 44 being provided for holding it normally awayfrom the disc.

The pasting disc 23 and paste feeding drum 16 are driven through gearingor other convenient means at suitable speeds depending on the conditionsunder which the device is required to operate. For example, the pastingdisc may be driven through gears 32, 33, 34, from the spindle 36 whichlatter is provided with a bevel gear 3'7 meshing with a bevel 38 on thespindle 39 coupled to the drum spindle 40 by a clutch 41. It will beunderstood that the teeth of the rotatable feeding drum act to mill thepaste which is thereby softened and given a consistency suitable for thepurpose in View, and the paste is then forced or pumped into the nozzleby the pressure of the tooth faces.

The feeding drum may, if desired, be made of cylindrical or otherdesired shape and it will also be understood that the invention may beapplied to mechanism adapted for use with ordinary liquid or semi-liquidpastes.
